Chronic Wasting Disease (CWD)

What You Should Know

  • Indiana DNR has detected two confirmed cases of chronic wasting disease (CWD) in wild deer – one in LaGrange County and one in Posey County.
  • There are no management actions that have been shown to cure, prevent, or eradicate CWD once it’s established. Indiana DNR’s response plan focuses on monitoring the spread of CWD to inform hunters and enable Hoosiers to live with the presence of this disease in deer.
  • The positive deer in Posey County was detected in an area of the state that is not known to have CWD nearby; therefore, DNR is implementing a CWD Enhanced Surveillance Zone in Posey, Gibson, and Vanderburgh Counties to find the percentage of deer that are positive for CWD in that area and to understand where the disease is.
  • DNR will continue to make CWD testing available at participating Fish & Wildlife areas, State Fish Hatcheries, and National Wildlife Refuges during deer hunting season.
  • Currently, no evidence suggests that CWD can infect humans.

About Chronic Wasting Disease

Chronic wasting disease (CWD) is a fatal infectious disease that affects the nervous system in white-tailed deer. It is caused by misfolded prions that damage the brain and nervous system. Other similar prion diseases include mad cow disease and scrapie in sheep. CWD is contagious among deer through direct contact, contaminated environments, and bodily fluids. Prions shed by infectious animals can persist in the environment for many years.

CWD has been detected in free-ranging white-tailed deer in over 30 states including Michigan, Illinois, Ohio, Kentucky, and Wisconsin.

Indiana DNR staff collect tissue samples from wild deer year-round (hunter-harvested or reported sick/dead) to monitor the presence of CWD in Indiana.

Learn more about Indiana’s CWD surveillance history in the annual Indiana White-tailed Deer Report.

Indiana DNR’s Response Plan for CWD

Indiana DNR responds to a CWD detection when a wild deer tests positive for CWD within the state or within 10 miles outside the Indiana border. If the CWD positive case is found in or near an area that already has CWD, DNR will denote a CWD Positive Area and continue monitoring.

If the positive case is in an area where CWD is not already established, DNR will designate either a CWD Enhanced Surveillance Zone or an 18-month CWD Management Zone

CWD Surveillance

Hunters may drop off deer heads for testing at participating Fish & Wildlife areas or State Fish Hatcheries throughout the deer hunting season. For a complete list of locations and hours of operation, please view the interactive map and list of properties. If you make an appointment during normal business hours, a biologist may collect the sample while you wait.

Test results will be posted online for individual hunters to access when laboratory tests are complete. The DNR requests voluntary assistance from hunters in this effort. Participants will receive a metal tag reminiscent of historic confirmation tags as tokens of appreciation.

No fee will be charged for CWD testing of deer through this program.

Partner Incentive Program

Indiana DNR and the National Deer Association have started a program to collect samples for CWD testing with the help of taxidermists and meat processors. In the 2025-2026 hunting season, partners will be asked to participate based on available funding and coverage.

Participating partners will collect the two retropharyngeal lymph nodes found in the neck of white-tailed deer and provide the approximate age of the deer. DNR will pay partners $10 for each viable sample they collect and will provide sampling supplies and training to all participating taxidermists. Partners will use a provided sample datasheet with corresponding barcoded stickers to record the information that needs to be collected from the hunter.

Hunters will be able to look up the results of their deer’s CWD test online three to four weeks after the samples are collected from the partner.

Carcass Transportation

Out-of-state deer hunters should follow carcass transportation regulations for their home state and carcass transportation regulations for the state in which they are hunting.

Import restrictions governing carcasses in Indiana

Human Health

There have been no reported cases of CWD infection in humans. DNR recommends that hunters have their deer tested and that people do not eat meat from an animal that tests positive for CWD. See the National Prion Disease Pathology Surveillance Center for more information.

For questions related to human health, contact the Indiana State Department of Health at 317-233-1325.
